Fig. 1From: Prognostic factors for medial open-wedge high tibial osteotomy with spacer implantation in patients with medial compartmental knee osteoarthritisSurgical procedures of spacer-type MOWHTO. The proximal fibular shaft was exposed by splitting the septum between the soleus and peroneus (a). The resected proximal fibula (b). A 3.5-mm guidewire was inserted 3Â cm below the knee joint toward PTFJ to determine the osteotomy plane (c). The proximal tibia was drilled on the osteotomy plane with a multihole parallel guiding apparatus and Kirschner wires [(d) and (e)]. Test models of different thicknesses were hammered into the osteotomy plane (f)Back to article page
